The invention relates to improvements in shocking machinesof the {typein which a freceive'rffor grain say, or the like, is moved rearwardlyfrom a shock forming platform and opened at its rear side for; dumpingthe shocks as they are completed,"such a machine being shown in CanadianPatents Nos. 192,- 523 dated September the 9th, 1913'; 285,215 dated the7th day ofAugust, 1923, and 235,- .584 dated the 3rd of November, 1923;In suchpatented machines the receiver for the grain was moved'rearwardlyand subsequently forwardly byendless driven side c'halns and Ihave-foundzthat sucha type of drive s notdependable and an object of thepresent invention is toprovide an improved and positive drivingmechanism for the grain receiver, which is at all times under thecontrol of the attendant and which is arranged so that it automatically.stops' when the grain receiver has reached-its limited forward orrearward position. I v

- A further obj ect'of the invention is to provide means associated withone of the driving pinions employed, Which I will engage with suchdriving pinion and 'hold"'it releasably looked after it has disengagedwith the'rack associated therewith, such insuring that the teeth of thepinion will subsequently mesh with the rack teeth. v v

' "With the above more important objects in View the invention consistsessentially in the arrangement and "constructionof parts hereinaftermoreparticularly described, reference being had to the accompanyingdrawings, in WlilC-lli i j Fig: 1 is a side elevation of'one side of themachine looking at it from the inner side, the rotatable platform whichcloses thebottom of the grain receiver being shown in vertical section,such section being taken at 15-1" Figure 2.

Figwl'i's a vertical sectional view'at' 4 1 Fig. 6 is a perspectiveviewof the catches controlling-the positions of the lever.

In the drawings above briefly described the numeral 1 designate'sthemain'wheeled frame of the machine including a pair of similar parallelvertical side frames 2. The numeral 3 designates the rotatable platformwhich normally closes the lower end of the upright cylindrical grainreceiver 4;, the grain receiver in'such position receiving grain and thelike from an attached harvesting machine (not shown). 1The sideframesaforesaid each comprisepzirallel upper, lower and'intermeediatebea ms 5, 6 and 7 which are suitably connected by uprights 8, andit willbe here obv served that the beam 7 stops rearwardly in' alocation approximately opposite the rear edge of the platform 3, whilstthe beamsfi'and 6 'projectrearwardly considerably therebeyond and formupper and lower guidetracks9 and 10,11t1lize'd to support two verticaland'paralhorizontally disposed lever bar '14: and an intermediatehorizontally disposed bar 15.

These carrier frames are carried by suitably disposed rollers whichoperate on the tracks 9 and 10, the top'bar 13 of thecarrier frame beingherein shown as "providedfwith two rollers 16 and 17 operated on. thetrack 10 and the lower corners of such frame beingprovided with rollers18 and 19 operatingon the track v9. I

The carrier frames support the grain receiver which ispositidnedtherebetween and suitably permanently attached to the-carrierframes such as by fastening bars 20, thearrangement being such "that thereceiver can ,2

move from its normally forward filling position over the platform 7'rearwardly to its discharging position at the rear of the platformp'ositioniand whilst The means employed for simultaneously andpositively controlling the movement of the carrier frames forms for thegreater part,

the substance of thepresent invention.

I-have hereinbefore mentioned: that their grain is delivered into theshock receiver from a harvesting machine and in so far as the presentdisclosure is concerned the harvesting machine frame is generallyindicated by the reference numeral 21, the side next the shocker beingsupported by a comparatively large bull or master wheel 22 as is Thebinder frame supports also a beam 23 parallel to'a-nd horizontallyopposite the beam 7. .The master wheel is fitted on the side next theshocker with a comparatively large internal driving gear wheel 24'suitably secured thereto in any well known manner so that such wheelwill rotate at all times with the master wheel.

The beam 23 and the beam 7 at the inner side of the shocker supportopposing bearings 25 and 26, which are secured permanently to theundersides thereof and receive rotatably a flanged sleeve 27 and a hub28, the hub being integrally formed with a pinion 29 and a clutch member30. A counter shaft 31 having one end circular in cross section and theother end square in cross section is provided, the circular end of theshaft being received rotatably within the hub 28, and the square end ofthe shaft being passed through a. square hole provided in the sleeve 27and having the protruding end thereof fitted with a pin-' ion 32.

The pinion 32 meshes continuously with the internal gear 24 and thepinion 29 operates 'on the horizontally disposed rack bar 33,

permanently secured to the underside of the intermediate bar 15 of theinner carrier frame. On the square end of the shaft 31 I mount slidablya shiftable clutch member 34 which is adapted to be broughtintoengagement with the clutch member 30 and such, causes the shaft 31to drive the pinion 29. The clutch member 34 is supplied with a.peripheral channel 35 for a purpose later described.

The beam 23 and the adjacent beam 7 also support top bearings36 and 37which receive rotatably a sleeve 38 and a hub 39, the latter sleeve andthe hub being constructed similar to the former and carrying a countershaft 40 similar to that 31. A pinion 41 is formed integrally with thehub 39 as is also a. clutch member 42, and the pinion is adapted toengage a rack bar 43 secured to theupper side of the inner bar 15 of thecarrier frame. The end of the shaft 40 remote from the pinion 41 isprovided with a pinion 44 which meshes continuously with the interialgear 24. A

.shiftable clutch member 45 is mounted on the square portion of theshaft 40 and is adapted when shifted into engagement with the clutchmember 42 to cause the counter shaft to drive the pinion 41. The clutchmember 45 is also supplied with a peripheral.

channel 46.

The harvester frame carries a controlling pivotally attach upper andlower operating bars 49 and 50, the operating bars extending towards theshocker and having the extending ends thereof pivotally connected tosimilar pivoted rocker bars 51, one of which is connected by a strap 52to the clutch'member 45, and the other by a. strap 53 to the clutchmember 34, the straps in both instances being received within thechannels of the clutch members. 7 p

According to the above arrangement it will be apparent that when theupper end of the lever is swung say towards the harvesting machine, theclutch members of the counter shaft 40 will be engaged, whilst those onthe counter shaft 31 will'be passed away from one anotherand that amovement of the lever 47 in the o posite direction will engage theclutch memb those of the shaft 40.

Means is provided for releasably locking ers on the shaft 31 anddisengage.

the lever in neutral and in its shifted positions, such emboding spacedstops 54 and '55 permanently secured to an adjacent frame bar 56, thestops being herein shown i'nthe form of angle brackets. When the leveris between the stops (see Fig. 6) the clutch members are in neutralposition, that'is, they are both disengaged. The attendant can release.

vions 59 and 60 which mesh with'similar tracks 61 and 62 permanentlysecured to the undersi'des of the lower bars 14 of the carrier frames.The forward end of the rack bar 43 has a number of teeth thereof removedas best 7 shown in Figure 1 and the rear end of the rack bar 33 has alsoa number of the teeth thereof removed and as appearing best in Figure 1.This arrangementis so that when the grain receiver is returning toitsnormal or forward position, the teeth of the then driving pinion 29 willclear or run off the teeth at the rear end of the rack bar 33, whilstthe teeth of the then idling gear wheel 41 are still engaged with theteeth of the rack bar 43 and such that in the rearward movement of thereceiver the teeth of the then driving gear wheel 41 will run off orclear from the 'teeth of'the forward end of the rack bar 43, whilst theteeth of the then idling gear wheel 29 are still engaged with the teethat the forward end of the rack bar 33.

obviously driven by the pinions 32 and 44 and as the lattercarrier'frame moves in either direction it causes the rotation of thepinion 59 which in driving the shaft 58' positively The carrier framenext the full wheel is smoothly drives the pinion 60 and accordinglysimul taneously shifts the other carrier frame in unison therewith. Withthis driving arrangement there is no possibility of the, carrier framesgetting out of alignment one with the other, and the drive isalwayspositive in either direction and such was not obtainable with the typeof chain drive shown in the patents hereinbefore mentioned.

As the pinions 41 and 29 are at all times directly under the control ofvthe lever 47 as the grain receiver is moving forwardly the attendantcan stop the carrier by shifting the lever to the neutral position, andfurther on account of the structural arrangement it is unnecessary forthe attendant to worry about the receiver when it reaches its foremostor rearmost positions, as the driving pinion automatically runs off theend of the rack which results in the stopping of the-movement of thecarrier frames until such time that the attendant shifts the lever tothe reverse position, at which time the movement of the carrier frameswill reverse.

I have provided means associated with the pinion 41 for releasablylocking the pinion in a set position immediately it runs off the forwardend of the rack bar 43, such insuring that when the rack bar issubsequently advanced under the driving action of the pinion 29, theteeth of the pinion 41 will go smoothly into mesh with the teeth of therack bar 43. The means employed comprise 1 a horizontally disposed bar63 having one.

end pivotally attached at 64 to the adjacent carrier frame and the otherend provided with a V-shaped catch 65 overlying the pinion 41. Anupright arm 66 is attached to the latter carrier frame and carries abracket 67 (see Figure 5) against which the bar 63 is resiliently heldby the action of the coil spring 68.

It will be observed that when the pinion 41 runs off the forward end ofthe rack 43 it is engaged by the catch 65 of the bar 63, which will holdit subsequently against rotation and which insures that when the carrierframe is subsequently advanced the pinion 41 will pass into mesh withthe teeth of the rack bar 43. Immediately following the intermeshing ofthe said pinion and teeth the bar 63 moves away from the said latterpinion, being carried forward with the carrier frame on which it ismounted.

Whilst I have shown a bar 63 as associated only with the pinion 41, Iwish it to be understood that a similar bar could be used with thepinion 29 to releasably hold it in place after it has run off the rearend of the rack bar 33.
